AUTOMATIC CLOSURE AND nisnvrno'rme SEAT-CABINET FOB. rangonosn'rs.

To all whom it may concern:

KINGH, a subject of the King ain and Ireland, residing at The Poplars, Quirindi, New South Wales, Australia,have invented certain new and useful Improvements in Automatic Closures and Disinfecting Seat-Cabinets for Pan-Closets, of which the following is a specification.

This invention relates to cabinets for pan closets and includes improvements in automatic seat aperture closures and disinfectant I sprinklers operated by canting the seat panel sprinkler is a sheet metal reservoir of 4 when the closet is not in use effectively fly proof.

'trat-ing the shutters,

which is mounted pivotally near its rear end, the canting movement being elfected by the imposition of the weight of a person on an the raising of such weight from the seat.

The aperture closure is a two leaf sliding shutter supported in guide runners in a cover which underlies theseat panel, and its operating means comprise a llnkage to the canting seat panel which brings the shutters together to close the aperture in the rising movement and moves them apartto open the aperture in the lowering movement of the panel. The disinfectant or deodorant angular section mounted on the back of the canting seat and fitted with a bent drip tube which is connected into the top of said reser- V voir sothat a drip of fluid disinfectant or deodorantis delivered only while the closet is in use. The sides of the cabinet and the cover are constructed of sheet metal, as also are the shutters and linkages and the disinfectant reservoir, and the fitting is such that the cabinet is drawings, Figure 1 the cabiand sides In the accompanying is a p rspeotive view of the top of net with the parts above their sides, and the operating linkages. Fig. is a longitudinal section through the upper part of the cabinet complete; Fig. 4 is a detail section illustrative of the mounting of the disinfectant dripper'; and Fig. 5 is a transverse section through the upper sides of the cabinet, the cover, and the slides and portion of the operating linkages.

The body portion 10 of the case or cabinet is a sheet metal box with its top edges rolled as shown at 11. This box is open bottomed and is set over an earth pan. The cover con sists of an apertured sheet of galvanized iron Specification of Letters Patent.

12 having four carrier lugs 13 which set over the sides of the cabinet, and two rearward whichcarry the seat pintles 36. This cover is hinged to the box 10 on pintles 47 and may be swung open to offer access to the pan. This plate 12 is stifiened by integral bent up rib pieces 15 at the side edges of the aperture, and it carries two slides 16 and 17 in which. the shutter plates 18 and 19 are movable transversely toward or away from each other. 20 is a wood stifiener bar. The slide shutters are upbent at each lateral edge as shown at 21 to form heckstops coacting with the flanges or ribs 15 which ar re turned downward as shown in Fig. 5 and at the meeting edges are flanged. to make an overlap or rabbet joint as shown at 23. The outer side edges 24 of the cover are inflanged between the carrier lugs 13 to set neatly within thecase sides (see'Fig. 5). o

The mechanism for operating the shutters 1819 comprises two lever arms 26 and 27 fulcrumed at 28 and 29 on the rear part of the plate 12 and slotted inarcs as shown to coact with the slide pins 30 which are fixed in the shutters 1819, and to offer the'necessary clearance to permit said shutters to be moved -by the swinging movement of said arms 26 and 27 about their fulcra 28 and 29. Each lever arm carries an angle lug 30 on a free pivot 31 laterally disposed relatively to the fulcrum pins 28 and 29. The downwardly projecting lugs of these parts are pivotally connected at 32 to the forward ends of curved push bars 34 and 35 secured at their rear ends to the seat panel 33. The seat panel is pivotally mounted at 36 in the wings 14. 37 is a filler plate which serves to close the gap between the .back end of the seat panel and the rear wall of the case, to prevent entrance of flies when the closet is out of use.

erating to sprinkle disinfactant into the rear part ofthe pan 44 when the seat panel 7 33is canted down, as when in use.

The operation is as follows. When not in use the seat panel 33 is canted up (see Fatented Mar. 11, 1919. 7

Application filed June 26,1917. Serial No. 177,006.

Fig. 3) by its counterweights 33 and the push arms 34 and are thrust forward, forcing the linkage levers 26 and 27 inward and thereby closing the shutters 18 and 19 as shown in Figs. 2 and is at the same time tipped back in the reservoir so that none flows through the tube 42 (see Fig. 3). When the Weight of a person is imposed on the seat panel 33 it is brought to the level position (see Fig. thereby causing the disinfectant to drip, and at the same time draWing back the arms 34 and 35 and thus spreading the levers 26 and 27 and so sliding the shutters 18 and 19 apart to offer an open aperture to the pan.

7 What I claim as my invention and desire to secure by Letters Patent is 11 automatic shutter operating mechanism for pan closet cabinets having an apertured pivotally mounted aperclose the aperture in the cover, and pivoted levers connected to said shutters and operaable by movement of the seat to open or close said characterized in that a pair of arms are fixedly connected at Copies of this patent may be obtained for five cents each, by Washington, D. G.

5. The disinfectant nautomatic shutter mechanism torpan closet cabinets having an apertured cover, a pivotally mounted apertured seat,

and shutters operable by movement of said seat to open and close the aperture in the cover, characterized in this, that the side edges of the aperture in the cover are flanged and the side edges of are provided With flanges coacting With the being flanged to form a rabbet joint When the shutters are closed.
